TELESCOPE TECHNOLOGIES
NexRemote
™
Remote Control Software
Celestron has been in the forefront of computerized telescope
technology for over two decades. We have taken this expertise
in telescope technology one step further by introducing the
NexRemote™ Telescope Remote Control Software. NexRemote
allows the user to control their Celestron computerized telescope
from their personal computer. Every function that is normally done using the
telescope’s hand control can now be duplicated remotely from a PC or laptop. This
software was developed for Celestron’s telescopes that use the NexStar control
system. These include the NexStar SLT Series, Advanced Series, CPC Series and
CGE Series (NexRemote ships standard with CPC and CGE Series models).
NexRemote provides full emulation of every aspect of the Celestron Computerized
Hand Control including functions such as:
• All telescope alignment options
• Access to the database of objects
• User objects
• Hibernation
• Integration with popular planetarium programs
NexRemote has additional powerful new features that include:
• NexRemote voice output - Allows you to keep your eyes on the stars instead of
the LCD by enabling speech support.
• Select the objects you want to see and the order that you want to see them.
• Create and save custom tours using the NexTour feature.
• Reduce the effect of the laptop screen illumination on your eyes
using Night Vision Mode.
• Wireless control of the telescope with optional game pad support.
• Use your personal GPS device to interface with NexRemote using NexGPS™.
• Download the latest NexRemote updates online.
Contact your Celestron dealer to find out availability of upgraded models that
include NexRemote. NexRemote software comes with a RS-232 cable to connect
your Celestron telescope to a PC. The software can be also be purchased
separately as a kit from an Authorized Celestron Dealer (Item #93710). The kit
includes the NexRemote software and license, a RS-232 cable, and a Serial-to-
USB adapter.
StarBright
®
XLT — An Optical System Breakthrough!
Celestron has elevated its renowned StarBright
®
technology to an even higher level of light transmission
with the introduction of our optional StarBright
®
XLT
High Performance Optical System.
One of the most important factors in the evaluation of
a Schmidt-Cassegrain telescope’s optical system performance is
its transmission — the percentage of incoming light that reaches the
focal plane. The design of the XLT System accomplishes two crucial
objectives — 1. To develop a coating system that is optimized for visual
use and, 2. To optimize the coating system and optics for
CCD/Photographic imaging.
The StarBright
®
XLT High Performance Optical System design consists of:
1. Unique enhanced multi-layer mirror coatings
Our mirror coatings are made from precise layers of Aluminum (Al),
SiO
2
(Quartz), TiO
2
(Titanium Dioxide), and Si0
2
. Reflectivity is fairly flat
across the spectrum, optimizing it for both CCD imaging and visual use.
2. Multi-layer anti-reflective coatings
Made from precise layers of MgF
2
(Magnesium Fluoride), and HfO
2
(Hafnium Dioxide), which costs nearly $2000 per kilogram, Hafnium
results in a wider band pass than Titanium, used in competitive
coatings.
3. High Transmission Water White glass
Our Schmidt-Cassegrain optical systems with optional StarBright
®
XLT
coatings use Water White glass instead of Soda Lime glass for the
corrector lens. Water White glass transmits about 90.5% without anti-
reflective coatings. That is 3.5% better transmission than uncoated
Soda Lime glass. When Water White glass is used in conjunction with
StarBright
®
XLT's anti-reflective coatings, the average transmission
reaches 97.4% — an 8% improvement!
These three components of our StarBright
®
XLT coatings result in one
of the finest coatings available. The peak transmission for the systems
is 89% at 520 nm. The overall system transmission is 83.5% averaged
over the spectrum from 400 to 750 nm.
Introducing Celestron's Revolutionary SkyAlign
Pick three stars, any stars…
Aligning your telescope is easier and faster than ever.
Simply input the date, time and your location (GPS
models obtain all this information automatically) and
then point the telescope at three bright stars of your
choosing. You do not need to know the names of the
stars — you could even pick the moon or bright planets! The NexStar
computer system will figure out which stars were chosen and then align
the telescope. SkyAlign is standard with NexStar SLT and CPC models.
There is no need to point the telescope north or to level the optical tube.
The initial position of the telescope is irrelevant. This makes for a fast
and very easy method for aligning the telescope.
How does it work?
The NexStar
®
software with SkyAlign calculates the angles measured
between the objects and then compares them to the known angles
between objects. Using this method, the telescope determines what
objects were chosen. The display will tell you which three objects you
aligned to for confirmation.
CN16 GPS Accessory Kit
The CN16 will automatically establish your location by
downloading the exact time, date, longitude, and latitude
from one of many global positioning satellites orbiting the
Earth. The CN16 plugs into your telescope’s base Aux port
and adds an extra element of simplicity, convenience, and
accuracy to your stargazing.
